Homework Statement
1) Calculate approx. how many Cosmic Microwave Background-photons that you would absorb per second if you were in space.
The Attempt at a Solution
Ok, I know that the CMB-photons fit with a blackbody spectrum with T = 2.725 K. So the total amount of photons I find by using
n = beta * T^3, where beta = 2.03*10^7 m^{-3} * K^{-3}.
This is the amount of photons per cubicmeter, which is also the amount that would pass through my body (assumed spherical) per second.
Am I correct?
